[EXPANDSD] Join your external SD with internal SD!
WARN: For developer only.
attachment is the EXPANDSD script.
Why use it?
So many applications use /sdcard for mass data storage(gameloft, navigation...),
but I9100's internal_sd size is limit to 11G, so we need external_sd's space.
But these applications dosen't know how to use external_sd, old method is hack the apk for external_sd, but this will change apk's signature, and need smali/baksmali to work. My method work in system level, don't need change any apk file.
How to use:
1.make expandsd.ownhere dirctory in external_sd root directory.
2.move internal_sd's directory(for example:/gameloft) to expandsd.ownhere
use 'mount --bind' feature, bind external_sd's dir to internal_sd.
Because the sd card using fat32 partition format, the 'ln -s' command does not work, so the "mount --bind" is the only way to dynamically change the directory content.
